Can't sign and get into xbox update preview

I signed up for this and 2 days later I dloaded an update that clearly is the preview, but I can't use the link you provided. What's going on? I now can't get into a party or play with my friends and yet I can't invite them to the preview either. Double
whammy!

Hey I'm signed up to the previews but still can't get access to the preview forums just keeps coming up with page cannot be found yet I'm getting a message on Xbox live saying preview the Xbox one smartglass please someone help cheers

No, you can't get rid of any of the previews. All updates are permanent and can't be reversed.

Hey there GCS RyGuy!

Sorry to hear about the trouble you're having with signing in and out of Xbox Live when your Xbox App device connects. Are you currently part of the Xbox One Update Preview by chance? If so let's get you over on the
Xbox One Update Preview Forums so that the right team is aware of your trouble. While this issue is happening when your Android device signs in, it's still worth reaching out to the
preview team about.

Thanks!

Hello,

I have signed up for the previews and was accepted. Like others in this thread, I am unable to access the preview forums. I always get the message,

"Group Not found."

I've seen mention that some people can't access the forum with evidence that this is a known problem (the group apparently DOES exist) - does anyone have an answer???

Part of the deal of signing up to the previews was that feedback was to be given in the forum - I now have experienced some bugs and wish to give feedback - but can't. Seems unfair as this now looks like a one sided deal. (We give you updates with bugs -
you can't tell us about the bugs!)
